I'm actually not familiar with any error message like that in Ghost - most Ghost error messages have numbers associated with them, so if there's a specific error the number is the easiest thing to quote so we can find the exact message you're referring to.
SATA compatibility isn't a simple yes/no question - different machines have very different SATA host controllers, but for most machines Ghost works just fine through using the system BIOS to access the SATA disks. To understand any compatibility issue with your machines we'd need to learn a bit more about your specific hardware.
Probably the easiest way to get some diagnostic information out of Ghost is to load it up on your specific hardware, and once it has loaded press control-C to abort it. When you do this it will write out a file called GHOSTERR.TXT which contains all the hardware information Ghost is using to access the disks in your system; if you post that here we can look over it and perhaps see what the problem might be.
